Abstract

Ionic liquids are salts that are liquid at room temperature. They have attracted considerable attention as new materials. In this study, a transient short‐hot‐wire apparatus was prepared, and the thermal conductivity of 1‐butyl‐3‐methylimidazolium tetrafluoroborate ([bmim] [BF~4~]) was measured. The experimental temperatures were from 294 to 334 K, and the pressures were from 0.1 to 20 MPa. It was found that the thermal conductivity of an ionic liquid has a very small temperature and pressure dependence. © 2007 Wiley Periodicals, Inc.
